title: Bizarre parosteal osteochondromatous proliferation of a phalanx.
abstract: A rare proliferative osteochondromatous malformation of a proximal phalanx is described. This malformation may mimic the appearance of a sessile osteochondroma or parosteal osteosarcoma on X-rays and may be mistaken for a low-grade osteosarcoma on histology, with disastrous therapeutic consequences. We found that cryotherapy followed by local excision was adequate to remove the tumour.
